Propagation-based classification of linear magnetoelectric response in dielectrics
Eduardo Bittencourt, Elliton O. S. R. Brandão, Érico Goulart +1
We study electromagnetic wave propagation in homogeneous dielectrics endowed with a linear magnetoelectric (ME) response in the geometric-optics regime. Assuming isotropic permitti…
From disformal electrodynamics to exotic spacetime singularities
Eduardo Bittencourt, Ricardo Fernandes, Érico Goulart +1
We study different types of spacetime singularities which emerge in the context of disformal electrodynamics. The latter is characterized by transformations of the background metri…
Light propagation in (2+1)-dimensional electrodynamics: the case of nonlinear constitutive laws
Eduardo Bittencourt, Elliton O. S. Brandão, Érico Goulart
We scrutinize the geometrical properties of light propagation inside a nonlinear medium modeled by a fully covariant electromagnetic theory in -dimensions. After setting the n…
Light propagation in (2+1)-dimensional electrodynamics: the case of linear constitutive laws
Érico Goulart, Eduardo Bittencourt, Elliton O. S. Brandão
In this paper, we turn our attention to light propagation in three-dimensional electrodynamics. More specifically, we investigate the behavior of light rays in a continuous bi-dime…
On the intrinsically flat cosmological models in a lattice
Eduardo Bittencourt, Leandro G. Gomes, Grasiele B. Santos
In this manuscript we investigate the intrinsically flat (space-flat) spacetimes as viable cosmological models. We show that they have a natural geometric structure which is suitab…
Galaxy rotation curves in the light of the Spinor Theory of Gravity
Mario Novello, Angelo E. S. Hartmann, E. Bittencourt
We analyze the recently obtained static and spherically symmetric solution of the Spinor Theory of Gravity (STG) which, in the weak field limit, presents an effective Newtonian pot…
